The invention relates to window ambs and window screens therefor, andmore particularly to guide means associated with the Window jambs formaintaining a screenin more than one position. 1 It iscustomaryto'providevwindows with fly screens in the summer time andsometimes with Ventilating 'screens in the winter time, and such-screensinconnnon use may be kdivided into two general classes or groups, asfollows:

Custom built screens of rigid frame construction which are built toorder to fit a particular window, and vwhich may be full length screenscovering both window sashes, orhalf screens covering the lower sashonly; and

Stock window screens which may be laterally adjustable, so that one sizeof screen may fit ya variety of sizes of window jar-nbs@ The. custom'b-uiltv screens, eitherA half or full'length, are relatively expensivedue to the fact that they are built to order to -fit ay particularwindow` and 'consequentlyA they have not been used to any extent inthemore modest homes; Moreover, 'when such screens are mounted in the-windowthey arefusuallyj left undisturbed for the entire season, as' vitis inconvenient 'and troublesome to` remove them. Therefore thewindowsfcovered. by such screens usually gounwashed forthe en-v I tireseason, and the perform-rance of such acts aswatering plants in windowboxes, adj-ustingawnings, etc., must be done from the eX- terior of thehouse,v1n`stead of being accomplis'hed much ymore conveniently fromtheinterior through the open wind-owl Stock screens are 'more often vof.the laterally adjustable type, for the reasonthatfwhilewindow j ambsaremade in various standard.

, sizes, it hasbeen found in actual practicefthat' window openingsl ofthe same standard size vary as much as three-eightsloffan inch, and thatthe horizontal and vertical amb mein-` bers are nearly considerably outof plumb, thatis, they are notat right angles toeach other. Y v i jTherefore the useof a non'fad'jus'table stock screen ofrigid frameconstruction, supposed- Y ly .adapted to it a standard size' window ,ljar'nb opening, results in practically asexremovedl from the window ambor guides if pensive 4a yproposition as the use of custom built screens.

'p A soecalled hump-spring style of sliding half screen has been incommon usage,1and embodiesUshaped spring members at the sides of thescreen and frictionally engaging guides on the windowjamb for thepurpose tionedunderi the upper sash between ,thev 7o-f parting stripsand vthe inside stop strips of the windowj amb. Thus the screen must betaken out of the window j amb every time vit is desired to close thewindow or'reachout' ofthe Vlower sash window opening from the insidethereof` Y y Accordingly suchscreens do not possess the advantages ofvpermitting theopening and 'closing ofthe window without removing thescreen, as in the case of custom-bi1`iltscreens fitted in the window.jarnb on the outside of the sashes'. t Y

' 'It' has been proposedY to mount such an. l

adjustable screen in retaining guides secured 85 tothe parting strip,and while such an ar-y rangement permitsmovement ofthek lower sash`,gitrequiresthey cutting of slots iny the r`parting strip of the'uppersashfto permit loweringy of the upper sash. 'llhis'is a rela- 90 tivelydificult operation since the slots ymust be cut the size and shape ofthe retaining guides and'since the' guides must have `sufficientclearance in the slots to permiteasy movement ofl the upper. sash, andyet not enough clearance to admit-,flies and smaller insects: Ivladen-Boiler, with eithertype of adjustablescreen above described,thes'creen mustbe info I facturer or dealer to keep a large stock .ofVstandard size screens on hand for each standard size of window jamb,thus materially reducing the cost to the consumer.

Another object is to provide guide means for mounting the screen, whichguide means may be secured in any window jamb outside of thvI windowsashes, so that each sash may be raised and lowered without disturbingthe screen.

A further object4 is to provide guide means which may be mounted in thewindow jamb for slidably mounting a stock screen of rigid frameconstruction, whereby the screen may be raisedor lowered to permitwashing of the window panes, or to permit reaching out of the windowopening from the inside, without removing the screen from its guides.

A still further object is to provide means for maintaining the screen inits up or open position in the guides, without depending upon springs or`frictional engagement with the guides.

And finally, it is an object of the present invention to provide guidemeans for slidable stock screens, which means are simple and inexpensiveto construct, and which combine the advantages attained by the use ofcustom 4built screens and adjustable stock screens.

l upper channel member increasing in width from top to bottom to form anangularly disposed channel for permitting withdrawal of the screen, andadjustable retaining mean-s at the bottom of each upper guide channelfor maintaining the screen in its raised position if desired.

A preferredy embodiment of the invention is illustrated in theaccompanying drawings Y forming part hereof, in which Figure 1 is anelevation of the exterior of an ordinary double sash window, showing theimproved screen slidably mounted in the guides in closed position;

Similar reference numerals refer to similar parts-throughout thedrawings.

` rlhe improved guide to which the invention pertains is adapted to bemounted in a window frame of usual construction indicated generally at10 and having' the side frame members 11, a top frame member 12 and asill member 13. The frame members have attached thereto in the usualmanner the parting strips 14, the outside guide strips. 15, and theinside guide strips 16.

The improved guide members are indicated generally at -17 in Figs. 1 to8, and preferably include upper guide channel members 18, and lowerguide channel members 19. Each guide member 17 is preferably secured asby means of nails or screws to the outside guide strip 15 of each framemember 11.

' The window frame 10 preferably encloses an upper sash 2O slidablymounted in the channel formed between the inside guide strip 16 'and theparting strip 14, and a lower sash 21 slidably mounted in the channelformed by the outside guide strip 15 and the parting strip 14.

Each llower screen frame guide member 19 is U-shaped in cross sectionand of uniform width throughout its length, and has side flanges 22 and22 and the web 23. The width of each member 19 is such that the flanges22 and 22 will slidably engage the side frame member of the screen whenthe latter is inserted therein. Each web 23 has apertures 24 formedtherein and is secured to one outside guide strip 15 at the side of thewindow frame in such a position that the plane of the outside face ofeach flange 22 substan-l tially coincides with the plane of the inneredge ofleaeh strip 15, sov that the lower 'ends of the guide members 19abut 'the sill 13, and so that their upper ends preferably terminatebelow the upper sash when the lsame'is located in closed position. p Y jEach upper screen frame guide member 18 is U-shaped in cross section,having the sider flanges 25 and 25 and the web 26, and tapers from awidth at its upper end substantially equal to that of guide member 19 toa width substantially twice as great at its lower end. Each web 26 hasaperture-s 24 formed therein for attaching the same to an outside guidestrip 15, andthe guide members 18 are positioned above guide members 19so that the outside face of each flange 25 substantially coincides withthe plane of the inner edge of each strip 15.

The lower end of each upper guide member 18 is preferably notched as at27 to receive the upper end of lower guide member 19, and the guidemembers 18 and 19 are positioned on the strips as shown in Figs. 5 and 7so that their flanges25 and 22 respectively form a continuous guideflange for the screen frame, which guide flange will just clear the sashwhen the latter is moved up or down; Each upper guide member 18 ispreferably of such length as to terminate below the top of the Windowframe when positioned so that its lower end abuts the upper end of guidemember 19. Y i

AnvL shaped screen retaining member 28 1s K pivotally mounted as at29upon the lower portion of each side flange of each guide member 18.Each side flange 25 is bevelled as at 30 to permit the member 28 to beswung downwardly, and the Vdepending web portion 31 formed by the notch27 acts as a stop to limit its downward movement, as best shown in Fig.3. Vhen the member 28 is in its down or screen retaining position,(Figs. 2 and 5) the lower endthereof is below the upper end of the outerflange 22 of the lower guide fmember 19.

The screen indicated generally at 32 is preferably of the non-adjustablerigid frame construction disclosed in my prior Patent No.

1,708,363, dated VApril 9, 1929, for window screens, but other types ofstock screens might be used without departing from the scope ofv thepresent invention. n

The screen 32 may be manufactured in such sizes for standard size windowjambs as will 'v give a substantial clearance between the screen frameside members and the outside Vguide strips 15 of the window frame, sothat when the screen is inserted in the screenvguides 17, the variationsand irregularities Y in the window jambs will be compensated for,-

and the clearance between the screen frame and the web members of thescreen guides will be covered by the side flanges of the guides. f

Thus the manufacturer or dealer is enabled to keep a-large stock ofscreens for each standard size of window jamb, and he may convenientlystock large quantities in the -offsea-` son, which will materiallyreduce. the cost to the consumer, as compared with the method' of makingscreens toV fit each particular [win-z dow. f In Figs. land 2'the screen32 is shown slid-rv ably mountedin the guides 17 and in lits low-4v eredor closed position with its top frame member closely adjacent the lower.meeting rail 33 of the upper sash, so as to substantially prevent.insects. fromentering intov the housefbetween the screen and the meetingrail.- rlhe retaining members 28 are shown vin their screenretainingpositions.

The screen 32 may be easily raisedv at any sev time, its side framemembers slidably engag person on the inside to reach out through v y'the rwindo-wopening for the purpose of wa! n tering plants, adjustingawnings, and the like. When the screen is thus retained in raisedposition 'by the members 28, the upper ends of the flanges 22- act aslateral stops to hold the lower portion of the screen away from theinner flange 25 ofthe upper guide member 18.

If it is 'desiredto remove the screen from the window, for washing thewindow panes,

the sanieinay be accomplished by raising the x 'Y 'i screen 32 teclearthe lower guide member 19, and rotating the stops 28'y to the 1positionshown in Figs. 3,6, 7 and 8, when by pushing outwardlyfon the lower endof the screen the same may be withdrawn angularly past ythe top of theguide 19in Ithe manner. shown in Figs. Gand 7'. W H 5 In the same manner'serted nin the guides.' p i Since-the frame guide members '17 v.aremounted upon the outside window'guides the screenmaybe in-A V15, bothsashes may beraised and lowered at will without disturbing the screen sothat the present improvement vpossesses the advantages of custombuiltscreens. l

It will be seen thatrthe present arrange mentk attains all theadvantages'of custom builtand of adjustable screens, andthescreenguidemembers may 'besiinply and economically manufactured.
